Prism is a modular Swift package for building production-quality Apple-platform apps. Rather than a monolithic framework, it ships as seven focused modules that you can adopt individually or together. Whether you need a token-driven SwiftUI design system, a type-safe HTTP layer, a unidirectional state architecture, or on-device machine-learning inference, Prism provides each capability as a clean, dependency-minimal target.

​
Module architecture

All seven modules sit in a layered dependency graph. PrismFoundation is the zero-dependency core that every other module builds on. PrismUI pulls in both PrismFoundation and PrismArchitecture. The Prism umbrella target re-exports everything with a single import.

Key features

Strict concurrency. Every public API is annotated for Swift 6 strict concurrency — Sendable, @MainActor, and actor isolation are enforced throughout. You get compile-time safety for async code without runtime surprises. Token-driven design. PrismUI uses six semantic token types (color, typography, spacing, radius, elevation, motion) to drive every visual decision. Swap themes at runtime without changing a single component call site. Accessibility by default. Components meet Apple HIG guidelines, support Dynamic Type and VoiceOver, respect the accessibilityReduceMotion environment, and ship with WCAG contrast-ratio validation via PrismAccessibilityTest. DocC on every public API. Every public symbol has DocC documentation with examples. Run make docs-serve to browse the full reference locally. 788 tests across 149 suites. The test suite covers unit, integration, snapshot, and architecture tests. PrismTestStore gives you synchronous assertions over state mutations in PrismArchitecture.
